UNITED STATES PATENT Orrrcag ALBERT CHARLES PAIN, OF BIRMINGHAM,ENGLAND.

SYSTEM OF LUBRICATION.

SPECIFICATION forming part of Letters Patent No. 498,689, dated May 30,1893. Application filed April 26, 1892. Serial No. 430,803. (N e model.)Patented in England May 13, 1890, No. 7.397.

England, have invented an Improved System of Lubricating'the WorkingParts of Steam or other Engines, (for which I have obtained patent inEngland May 13, 1890, No. 7,397,) of which the following is aspecification.

My invention consists in an improved construction and arrangement ofdevices for luence to the accompanying drawings the manbricating theworking parts of steam or other engines whereby not only are thebearings lubricated in the most efficient manner, but

improved system of lubrication applied for the smooth working of theengine is greatly facilitated so that it is possible to run doubleacting engines at speeds considered'practica ble with single acting onesonly In my improved system the ordinary oil cups are dispensed with, theoil, water-or other lubricating liquid being introduced to the ,va-'rious bearings under pressure from a pump, accumulator or high leveltank bya continuous system of oil ways, drilled through the shaft orjournal, with holes radiating therefrom to the surfaces to be lubricatedas hereinafter described.

The bearing and Working parts are inolosed in a suitable casing notshown in the drawings which may or may not form part of the engineframing, and the lubricating fluid escaping from the journals is therebyprevented from being thrown about and is returned into the basin orsave-all from which the pump takes its' supply. The bearings may befitted with packing or other device for retarding the escape of thelubricant if considered advisable.

The advantages derived from the application of my new systemare:-+Firstthat the lubricant being introduced under pressure willimmediately fill any spaces that may exist between the journal andbearings and thus conduce to the smooth working of the engine, and thesaid engine may be run at a higher speed than hitherto found practicablewithout knocking. Secondthe bearings are very efficiently lubricated, afilm of oil being constantly maintained between the surfaces whereby theloss of power due to friction is reduced to a minimum and wearing ofjournal or other bearings prevented. Thirdthat the constant passage ofthe lubricant fluid between the surfaces of the hearing has aconsiderable cooling effect. Fourthon account of the application ofpressure a cheaper form of lubricant may be used having less body.Fifththat when the pump is driven directly by the engineitself thesystem of lubrication-becomes essentiallyautomatic and the engine may berun continuously for long periods andwith a minimum of attention.

I will now proceed to describe with referner in which my invention is tobe practiced. Figure 1 represents in vertical section my the purpose ofillustration to the principal bearings of an ordinary vertical singlecrank steam engine and Fig. 2 represents in section an elevation thecross head bearing and'guide shoe of the same, the sectional part ofFig. 2

/ being taken in a plane at right angles to that in which thecorresponding part" of Fig. l is taken.

The same of letters of reference indicate the same parts in bothfigures.

A is the crank shaft; B the crank pin bearlng.

(l, O are the two main bearings on either side of the crank pin bearing13.

D is the eccentric sheave; E the cross head bearing and F the cross headguide shoe best seen in Fig. 2.

In the crank shaft A the continuous central oil Way G, G, G is drilled.From this central oil way other oil ways radiate marked respect- I ivelyO, 0', O and 0 It will be seen by an examination of the drawings thatthe branch or radial oil ways 0 and O convey the oil from the centralway G to the two main bearings O, C of the crank shaft and the radialoil way 0 conveys the oil to the eccentric sheave D while the radial oilway 0 conveys the oil to the crank pin bearing B. Each of the radial oilways 0, O and 0 opens and delivers the oil to circumferential or annulargrooves M and-M turned in the inner surfaces of the respective brassesor bearings as represented in the drawings.

The lubricant under pressure produced by a pump, hydraulic accumulatoror high level tank is introduced at one end of the central oil way G bya pipe H connected to said oil annular grooves in the interior of thebrasses B, O, O and to the eccentric sheave D whereby theefficientzlubrioation of thesaid brasses and sheave is produced.

Instead of conveying the oil orlubrican t under pressure direct to theend of the main 1 or central oil way as represented in the drawings thesaidoilor lubricant maybe conveyed first through holes drilled in thecaps and brasses of:-one orboth ofathe mainbear-in'gs 0,0

and communicating with the circumferentialorgannular grooves M, M andthence by the ra dial or zbra nch oil ways 0, O. to the centraloilwayGand parts in connectionherewith. The f lubricating. fluid, may be.introduced. to. the continuous system of channels, at any. other pointwhioh the exigencies of, the particular design may render desirable.When the cross head-pin bearingris to belubricated from the oil aywhi h;he. a k. h ft b ar ngs and. nt i heave r ub icat the. r anInentrepresented in Fig. 1 is employed.

the face of the guide shoe F, Fig. 2. The

face of the other guide shoe not represented is lubricated in a similarway. Thebearing of thecross head. pin. and the, faces of the guide shoesare thus efficiently lubricated.

The surplus lubricating oil or fluid escap- 1 ing from the bearingsandother working, parts may be collected in a save-all not representedinthe drawings from which saveall the pumpfeeding the main oncentral oilway and the oil ways and pipes in communication with it takes itssupply.

By the method described and illustrated of lubricating the bearings andworking parts got, steam or other, enginesztheadvantages obtained overthe ordinary system have hereinbefore been pointed out.
